The Nitropolis 3 slot starts with 6 reels, 4 rows and 4,096 ways to win. Wins are created by landing 3 or more matching symbols on consecutive reels starting from the reel 1 (the leftmost reel). Symbols can land in any position on the reels but need to be on successive reels basically.

There is a ‘Coins’ icon at the bottom of the screen which, when selected, will display all 12 available bet options. Go to the ‘Settings’ tab to enable Quick Play. There’s also an Auto Spin facility. The latter 2 extras are not available to UK players.
Like with all ELK Studios slots late, the Nitropolis 3 RTP is 95%. This is below the 96% online slots average but becoming the trend since 2021. The volatility is medium to high (7/10) with wins landing on average every 5.2 spins. The hit frequency rate is 19.2%.
In terms of payouts, the maximum exposure/win is 50,000 x your total stake. This makes Nitropolis 3 the best paying slot potentially in the ELK Studios catalogue. Previous Nitropolis games offer 10,000 x bet max wins.
Theme – nitro gangs are back for a 3rd adventure
High Value Symbol: Dawg Boss
Compatibility: Mobile, Tablet, Desktop
With a dystopian theme, the Nitropolis 3 slot is the 3rd game in the series, following on Nitropolis and Nitropolis 2. The story Is that the Nitro gangs were overwhelmed by Sergeant Nitro Wolf and had no choice but to jump in their blimp and flee the city of Nitropolis. In order to live their dog eat dog lifestyle, they’ve gone south to a tropical beach with Nitropolis not too far in the distance.
There are palm trees, a deck chair, a thatched beach parasol, a lifeguard hut and toxic waste barrels. The soundtrack is upbeat but has a happier feel compared to the ones in the previous Nitropolis slots. It’s a little odd for a post-apocalyptic world and nothing like you’d expect to see (think I Am Legend movie starring Will Smith).
On the reels you’ll see low value A, K, Q and J royals. The medium value symbols include the Rogue Rats, Pug Thugs, Gritty Kitty and Dirty Dawgs clan emblems. The higher value symbols are represented by the leader of the 4 clans. In order of value, you have the Rat Boss, Pug Boss, Kitty Boss and Dawg Boss. The Dawg Boss is the best paying symbol giving you 1.5, 3, 4 or 5 x your total bet for 3, 4, 5 or 6 in combination.
There is also a toxic sign and cocktail wild symbol which substitutes for all symbols except the Bonus, Super Bonus, Both Ways, Redrop and Nitro feature symbols.
|J||3, 4, 5 or 6 = 0.1, 0.15, 0.2 or 0.3 x stake|
|Q||3, 4, 5 or 6 = 0.1, 0.15, 0.2 or 0.3 x stake|

Nitropolis 3 Mobile
With ELK Studios being a mobile-first provider, all their games are producing with HTML5 technology. This means Nitropolis 3 can be played on iOS, Android and Windows operated mobile devices. It’s also available on tablet, laptop, PC and MAC devices. With up to 1 million ways to win (more details below), a larger screen is always recommended.
Nitropolis 3 Bonus Features
The Nitropolis 3 slot has 11 bonus features. With avalanches and increasing number of rows/ways to win, there are big symbols and Nitro Reels. The latter adds extra 1×1 or 2×2 symbols which can increase the number of ways to win up to 1 million. With Nitro features enhancing your gameplay, there are free spins where the number of rows/ways to win can only increase. The Super version sees you play the maximum 8 rows and both ways pays.
When you land a winning combination, the Avalanche feature comes into play. All symbol that are part of a win explode and leave space for new symbol drops. An addition row of symbols is then added at the top with up to 8 rows possible. You would need 4 consecutive avalanches to play with the maximum 8 rows. The more rows, the more ways to win with up to 262,144 ways to win possible.
Another win will give you another avalanche which then continue until you don’t get a win. Once this happens, you’ll play on the default area of 6 reels, 4 rows and 4,096 ways to win. Here’s a table showing you the number of ways to win per row:
|Rows||Ways to Win||Calculation|
Big Symbols feature
Like in Pacific Gold, all paying symbols and wilds can appear in 1×1, 2×2, 3×3 and 4×4 sizes. For example, a 4×4 Big Symbol will consist of 16 individual symbols. This is called the Big Symbols feature and increases your chances of landing a win.
Nitro Reels feature
Up to 1 million ways to win is possible
Like with the previous Nitropolis slots, there’s a Nitro Reels feature. Small Nitro Reels cover 2 symbol positions and contain 4, 6, 8, 10 or 12 1×1 paying symbols. Big Nitro Reels cover 6 symbol positions and contain 2, 3, 4, 5 or 6 2×2 paying symbols.
In essence, this gives you more ways to win. There’s up to 1 million ways to win at its maximum configuration. You will see the number of ways to win above the reels for each spin.
Furthermore, there are various symbols that can land on the reels which trigger Nitro features. Here is information on all 5 of them:
|Redrop||Bonus symbols and Nitro feature symbols remain for the redrop with the Nitro Reels respinning|
|Both Ways||All ways pay left to right and right to left (double payouts)|
|Nitro Match||Nitro Reels on same and adjacent reels reel as this symbol match with an adjacent reel symbol|
|Nitro Upgrade||Nitro Reels on same and adjacent reels as this symbol upgrade with extra symbols added|
|Nitro Wild||All symbols in the Nitro Reels on the same and adjacent reels as this symbol are replaced by wilds|
Bonus Game feature
The Bonus Game feature is triggered by landing 3, 4, 5 or 6 blimp bonus scatters. This will award 8, 12, 16 or 20 free spins respectively. Importantly, all Nitro Reels are sticky for the duration of the feature. When a new Nitro Reel appears, they stack on top of each other.
There’s a Safety Level feature meaning the new of rows and ways to win will not drop below the current active safety level. This means the number of rows/ways to win can remain the same and/or increase.
With a full retrigger available for up to 40 free spins, triggering the Bonus Game feature with a combination of blimp bonus scatters and Super blimp bonus scatters will see you play the Super version. You will play on 8 rows and the Both Ways feature activated. This dramatically improves your payout potential.
Lastly, there’s an X-iter feature which allows you to buy your way into 5 game modes. Not available for UK players, they will set you back between 2 and 500 x your total stake. Here are your options:
|Boosted Bonus Chance||2 x stake||1 spin with more then double the chance of triggering the free spins|
|Big Nitro Reel||10 x stake||1 spin with a big Nitro Reel guaranteed|
|Nitro Match||25 x stake||1 spin with a guaranteed Nitro Match with both ways pays|
|Bonus Game feature||100 x stake||Entry to free spins|
|Super Bonus Game feature||500 x stake||Entry to super free spins|
Nitropolis 3 Review Summary – 5 times bigger wins available
The Nitropolis 3 slot follows the same formula used by ELK Studios in the previous Nitropolis games. Offering Nitro Reels and extras like both ways pays, there’s a few new additions like Nitro Match and Nitro Upgrade.
There are some similarities with Pacific Gold as the free spins both offer up to 8 rows with 262,144 ways to win and a Safety Level feature. The difference here is that the Nitro Reels can give you more ways to win that the slots starring adventurer Kane. Saying that, Nitropolis 2 offers over 191 million ways to win as opposed to 1 million here in the 3rd edition.
However, Nitropolis 3 offers max wins of 50,000 x your total stake per spin which makes it ELK Studios most lucrative slot to date. The 2 previous games in the games offer 10,000 x bet max wins. That’s 5 times lower than this release. Here’s a quick table to compare the 3 Nitropolis slots:
|Slot||RTP||Max Ways to Win||Max Win||Bonus Features||Hit Frequency|
|Nitropolis||95%||85,155,840||10,000 x stake||4||19.8%|
|Nitropolis 2||95%||191,102,976||10,000 x stake||12||20%|
|Nitropolis 3||95%||1 Million||50,000 x stake||11||19.2%|
Graphically, Nitropolis 3 is softer than its predecessors and takes place on a beach as opposed to the thick of the action in the post-apocalyptic city. I think ELK Studios has added some good extras but incorporated elements from the previous game and from other titles to create a much harder hitting slot that will surely turn some heads.
I personally prefer the gameplay in Nitropolis 2 but the max win potential in the 3rd installment is 5 times higher. For that reason alone, Nitropolis 3 is sure to become the most popular game in the series.
